This patch adds spk_io_ops struct which contain those methods whose job is to
communicate with synth device. Currently, all comms with external synth
device use raw serial i/o. Starting with this patch set, an alternative
tty-based way of communication is being introduced. The idea is to group all
methods which do the actual communication with external device into this new
struct. Then migrating a serial-based synth over to tty will mean swapping
serial spk_io_ops instance with tty spk_io_ops instance, making the migration
simpler.
At the moment, this struct only contains one method, synth_out but more will
be added in future when incorporating inputs in the tty-based comms. Also at
the moment, synth_out method has one implementation which uses serial i/o.
Later in this patch set, an alternate tty-based implementation will be added.
